Abstract: A power source (14) rotates an eccentric (20) engaged within the center of a relatively large drive roller (22) to rotate the drive roller while simultaneously orbiting the center of the drive roller about a circular path so as to cyclically advance and retract from piston assemblies (24) located within pump assemblies (16a-16d). Rotation of the eccentric (20) causes each piston assembly (24) to cyclically advance against and retract from a flexible diaphragm (26) to cause fluid entering the pump assembly to be forced out under pressure Each diaphragm (26) is "backed" by a spring-loaded support (27) that resiliently pushes against the side of the diaphragm opposite the piston assembly.

Patent NO-163650-C (NO)
Inventor: KLAREN DICK GERRIT
IPC: F28D13/00
Filed: 1984-07-20
Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the innertube walls. Forthe downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so thatthe apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line.The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.

Abstract: Reaction of lignocellulosic material with acetic anhydride greatly improves dimensional stability and resistance to biological attack and is, according to the invention, made in the absence of any cosolvent or added catalyst and in a simple way. Partially dried or dry lignocellulosic material is treated with liquid acetic anhydride for a short period of time, the time being adapted to the dimension of the material used. In a fol­lowing step, any excess anhydride not impregnated into the material is removed. The impregnated lignocellulosic material is then placed in a heated chamber to yield acetylation to a predetermined weight gain. After a short period of time, again adapted to the dimension of the material, unconsumed acetic anhydride and byproduct ace­tic acid are removed from the heated chamber and reco­vered.

Abstract: A process for the production of beer with a low alcohol content is described. The process comprises preparing a wort by boiling and adding ascorbic acid to such wort prior, during, or after boiling, so long as the wort remains hot. The process can be employed according to the invention for the production of non-alcoholic beer by the yeast cold contact process, in which yeast recovered from a fermentation process is brought into contact with the wort at a low temperature below 0 DEG  C. As a rule, the non-alcoholic beer produced by this process imparts an unpleasant and bitter aftertaste. By adding ascorbic acid to the boiling wort, the bitter aftertaste is completely eliminated.

Abstract: A modified Phillips-type screwdriver bit is disclosed that is fully compatible with a standard Phillips-head fastener, and is designed to significantly increase the level of torque that can be applied to the fastener while at the same time substantially reducing the cam-out  forces normally  produced by  a  standard  Phillips screwdriver bit. These results are accomplished by forming generated surfaces along the side walls of the bit wings so that the included angle defined by the converging side walls of adjoining bit wings gradually increases from the Phillips standard 92 degrees at the base of the bit wings to approximately 105 degrees at the wing tips.  This configuration serves to confine the application of torque to the side surfaces of the bit wings initially along contact lines adjacent and parallel to the roots of the bit wings with the contact area gradually progressing  radially outwardly as  torque  levels  increase and the opposing side surfaces of the recess wings in the head of the fastener begin to deform.

Title: Procaine double salt complexes
Inventor: KOCH ROBERT
IPC: C07D213/80
Filed: 1990-03-13
Granted: 1999-03-16
Abstract: A procaine acid addition salt, wherein the acid is attached to the diethylamino nitrogen, is complexed with a biologically active organic acid such as a vitamin acid, essential unsaturated fatty acid, C4 to C6 hydroxycarboxylic acid or alpha amino acid in stoichiometric ratios of organic acid to procaine acid addition salt to form a double salt complex wherein the organic acid attaches to the p-amino nitrogen.  Such double salt complexes protect the procaine molecule from cholinesterase hydrolysis when orally administered to warm blooded animals allowing the complex to be carried intact to the site of damaged cells and across the cell membrane where the double salt complex is disassociated in the cell releasing the organic acid and procaine for cellular repair and regeneration. Procaine hydrochloride is the preferred procaine salt. Preferred acids are citric and vitamin acids including nicotinic acid, ascorbic acid, biotin and folic acid.

Title: Method and means for determining air mass in a crankcase scavenged two-stroke engine
Inventor: STILES STEVEN D
IPC: F02D41/02
Filed: 1990-03-16
Granted: 1994-02-01
Abstract: METHOD AND MEANS FOR DETERMINING AIR MASS IN  A CRANKCASE SCAVENGED TWO-STROKE ENGINE          Abstract of the Disclosure A method and means are described for determining the mass of air available for combustion within a cylinder of a crankcase scavenged two-cycle engine, without the use of a mass-air flow sensor. This is achieved by estimating the mass of air under compression within a crankcase chamber, prior to its transfer to a cylinder combustion chamber.  The estimate for air mass is based upon the integration of crankcase pressure over the interval of decreasing crankcase volume, while air within the crankcase is under compression.  The volume of the air within the crankcase chamber is derived as a function of engine cycle position, with crankcase air temperature being derived as a function of intake air temperature.  Air pressure during compression is monitored with a crankcase pressure sensor.  The estimate for air mass is corrected to account for air leakage and incomplete transfer of the air between the crankcase and combustion chambers.

Title: Anti-blister circuit
Inventor: SENDELWECK GENE KARL
IPC: H04N5/68
Filed: 1990-04-05
Granted: 2002-06-18
Abstract: An anti-blister circuit comprises a first detector for detecting amplitude excursions of a signal with luminance information beyond a white level threshold during each horizontal scan. This enables the circuit to be more sensitive by responding to excursions occurring during each horizontal scanning line. A first timer, responsive to the first detector, provides a first control signal related to a minimum duration of each amplitude excursion of the signal beyond the threshold. This enables the circuit to avoid controlling beam current, for example by reducing contrast, responsive to signal peaks which are too short to cause blistering or warping. Finally, a switch and second timer, responsive to the first control signal, provide a second control signal which falls at a first rate to reduce beam current, for example by reducing contrast, during each minimum duration amplitude excursion; and, which rises at a second rate to permit the beam current to increase after termination of the amplitude excursion, until the next minimum duration excursion. The time constant for the second rate is much greater than the time constant of the first rate.

Abstract: A surface impedance measurement device comprises a transmitting electrode producing a magnetic field in the area surrounding a material to be tested and a receiving electrode receiving the magnetic field. An electric voltage wobbled in frequency is applied to the transmitting electrode, and a circuit measures the voltage at the terminals of the second electrode.
